Thanks, @mjs271 ! Reviewers: I will let you know when it is ready for review. We need to run some more tests, which might bring in more changes. |

These mods are due to the mismatch in the mam4xx submodule. Once microphysics PR is merged, we will rebase to remove these mods.

Removed WIP to get it tested once. I will WIP it again after the testing. |

Looks like the model failed to download a data file: This file is present on the server at:https://web.lcrc.anl.gov/public/e3sm/inputdata/atm/scream/mam4xx/emissions/ne2np4/ I am not sure why the model can't download it. |
Stranger yet, the file appears to be on weaver already |
There was a PR that went in recently: #3080 (luca may have something to say) |

@mahf708 : Thanks again for the review. We have addressed all the comments except for the file reading (as we will revisit it later). I will create an issue for the other comment about using the scaling function. @mjs271 have tested on PM-GPUs and these codes are not generating any new warnings. This should be ready to merge now. |

CI: automerge
An existing EAMxx interface (
eamxx_mam_srf_and_online_emissions_process_interface.cpp) is modified to include the invocation of the "online" emissions of dust and sea salt. The new additions are for:Since the CMake option,
SCREAM_ENABLE_MAM, is alwaysON, these codes are always compiled with the EAMxx codebase, but this interface can be turned off/on using the namelist flags.Output variables
The output variable names are "constituent_fluxes" and interstitial aerosols whose emissions are computed:
nacl_a1,mom_a1,num_a1,nacl_a2,mom_a2,num_a2,dust_a3,nacl_a3,mom_a3,num_a3,mom_a4,num_a4Note that the "constituent_fluxes" indices are exactly the same as EAM's
state%q.Testing
We have existing tests for this interface, so we didn't add any new tests. We have a suite of validation tests in the MAM4xx repo to validate the online emission processes.
The
srf_online_emissprocess that invokes online emissions codes has to be invoked with theconstituent_fluxesprocess to modify interstitial aerosols. Otherwise, only theconstituent_fluxesarray will be modified. These processes are added as an EAMxx process with the ability to turn it on/off using the labelsmam4_srf_online_emissandmam4xx-constituent_fluxesin thenamelist_scream.xmlfile. Theatmchangecommand to invoke these processes in a CIME simulation is:To run a CIME simulation, we have created a test modifier
mam4xx-srf_online_emiss_constituent_fluxes:Where,
<machine>is the machine name<compiler>is the compiler to use on the machine<test id>is a unique string test identifier<project id>is the allocation project to chargeNew input data
We have added 6 files for each of the three grid resolutions:
ne2np4,ne4pg2,ne30pg2for soil erodibility (3 files) and marine organic aerosols (3 files)
For finer resolutions, the code will interpolate the
ne30pg2grid. All the files are on the E3SM input data server.Figures from model analysis
Aerosol burdens from surface emissions only simulation at ne30pg2 resolution. We have added prescribed emissions plots to show that they remain unchanged (plots generated by Meng):
NOTE: There is an initial unphysical spike in dust burden when we use ne4 resolution. @kaizhangpnl found that that the spike may be due to the huge jump in mean u10 velocity between 1st and 2nd time step (see his comments below). Here are plots from ne4 simulation (generated by Chandru)
Standalone Test Timings (Compy):
We will upload the timings once the PR is reviewed and approved
